1 This invention relates to garment pressing machines and particularlyto the mechanism therein for stripping a glove or the like garment froma form on which the garment has been mounted for pressing or stretchingpurposes.

The invention contemplates the provision of yieldable stripping meansself-.adjusting to variations in the thicknesses, -shapes and positionsof glove flat during the stripping operation and re-` leasing the gloveafter. it has been completely stripped. f

'The various objects of the invention will be clear from the descriptionwhich follows and from the drawings, in which Fig. 1 is a top plan viewof the stripping mechanism4 in the inoperative position thereof, theclamping plates being shown separated ready to receive the formtherebetween.

Fig. 2 is a similar view of the clamping levers and plates in thestripping positions thereof and showing the link for limiting theseparatingmovement of the plates.

` Fig. 3 is a front elevational view of the stripping mechanism.

Fig. 4 is a side elevational view thereof.

In the practical embodiment of the invention shown by way of example,`the form l0, having mounted thereon the glove or other garment lf, is.swung by any suitable mechanism such a-s is shown for example in mycop-endingapplication ior Garment stretching and pressing machine,Serial No. 638,073, between the two rows of` clamp` ing plates I2 and I3(Fig. 4). Each plate is preferably,l though not necessarily. in the'form of a disc having a knurled or roughened inner face intended to@usage the glove irctonally and. without Slimline disc is the supportrod lll, slidably mounted in one of the lever-s l5 or I6, and carryingthe compression. series ll. Whthvfses the plate inwardly toward the.verresnondns plate of the. other stellar lil rxed to the rod i4. and byits enf.

Extending axially from the l inward movement of the rod and of theplate:

thereon.

Each of the levers is swung toward the iorm I0 at the proper time, andwhile the form is at rest, to clamp the form and the garment thereonbetween the rows of plates I2 and I3. For this purpose, the lever l5 ispivoted as at IQ and the lever i6 is similar-ly piv-oted at 20 to theupper lugs 2| projecting transversely from the vertis callyreciprocating slide 22. The spring 2,3 joinf ing the left handends ofthe levers (as viewed inv Figs. 1 and 2), urges the levers into thepositions thereof shown in Eig. 1 and thereby urges the rollers 24 atthe right hand ends of the respective levers into engagement with thecorresponding upright cam plate 25., which serves as a iixed cam toswing the lever about its pivot into the posiev tion shown in Fig. 2.The cam plate 25 is secured to the frame 2E of the machine as by meansof= the vbracket 21 and is of the proper length to` maintain the platesl2- and i3 in their clampingand stripping positions until the glove iscome. pletely stripped from the form. Preferably, the plate 25 is bentlaterally at it-s lower end to pen vmitthe spring 23 to swing the leversI5 and lli` 'and the clamping plates carried thereby cute wardly at theproper time `to release the glove from the clamping plates.

' When so released, the glove drops on to the curved guide member 28suitably secured to the frame member 2B as by thebracket member 30,saidguide member being suitably curved to direct the glove toward thebelt 3|. The glove whenl released falls along the member 28, lying flatthereon, and drops in a flat position on to the belt 3 l, which carriesthe glove out of the machine.

To limit the extent of the movement of the plate-s l2 and I3, the link32 (Fig. 2) is secured to the levers I5 and I6 adjacent the spring 23.slots as 33, 34 being provided at the respective ends of the link.Passing through each of the slots and fixed to each lever is a pin 35which may move in the slot through which it projects, from one end ofthe slot to the other end thereof. When the pins are at the outer endsof the slots, further inward movement of the levers is pre. vented, andsimilarly, when the pins are at the inner ends of the slots, the leversand the plates thereon cannot be further separated.

sagement. with the lever, limits, the` extent of the In addition to theinward and outward move,-` ments of said levers and of the clampingplates alternately to grip and to release the glove, said levers andplates are also reciprocated verticallyby means which will now bedescribed. The slide-y 22 on which the levers areV pivotally mounted is;

provided with a T-shaped projection or guide 36 reciprocating in thevertical T-shaped slot or groove 31 provided between the spaced apartgib members 38 and 39 which are secured to the arm 40 of the framemember 26. For reciprocating the slide in the groove 31, the connectinglink 4I is pivotally secured at its lower end to the lug 42 extendingfrom the lower end of the slide 22, the link -being pivotally secured atits upper end to the crank 43 Xed to the shaft 44, said shaft beingrotatablymounted in the frame member 2E. It will Abe seen that when theshaft is rotated, consequent rotation of the crank causes reciprocationof the slide and of the levers and clamping plates as a unit.

Since the cam rollers 24 are preferably free to ride off the fixed camplates 25 controlling the inward and outward movement thereof, at thetime when said rollers approach the ends of upward reciprocatory strokesthereof, means are provided to carry the rolllers back on to the camplates as the descent of the slide is begun. It should be noted that therollers ride 01T the cam plates for the purpose of insuring maximumseparation of the clamping plates I2 and I3 for the proper entrancetherebetween of the form I which may vary considerably in size fordifferent gloves. As best seen in Fig. 4, the means for carrying the camrollers back on to the operative inner surfaces 45 of the cam plates 25comprises yieldable guide members each in the form of an adjustableplate cam 46 and each pivoted as by means of a hinge 41 to the plate cam25 at a point out of the vertical path of movement of the cam rollers. Aleaf spring as 48 secured to the plate cam 25, is provided with asuitably bent upper end part engaging the hinged plate cam 45 and urgingsaid cam against the stop 49. The stop is threadedly engaged by theadjusting nut 50 thereon and is adjustable to determine the angularposition which the cam plate 46 may assume, it being understood that theupper end of the plate 46 is arranged outwardly beyond the roller 24 sothat said roller on its descent engages the inner face of the guidingcam plate 46 and is forced inwardly thereby into position to ride on tothe inner surface 45 of the plate 25. Preferably, the angle of the plate46 t-o the vertical is about the saine as that of the lower end or tipof the form.

Said plate 25 is so arranged as to maintain the lever I or I6 in itsinnermost position during the descent thereof, in which position thelevers compress the springs I1 and f-orce the clamping plates I2 and I3inwardly into yieldable but pressed contact with the end portion of thepartly stripped glove. To initiate the stripping operation, the guidecam plate 46 first swings the levers I5 and I6 sufficiently 'to clampthe glove and the form I0 between the plates I2 and I3. As the slide 22descends, the plates I2 and I3 owing to their frictional engagement withthe glove, begin their stripping action, any movement of the levers inexcess of that necessary to clamp the plates I2 and I3 being taken up bythe springs I1. As the cam rollers 24 move along the guide plates 46,the levers continue to swing inwardly enough to maintain the pressureupon the clamping plates as said plates follow the contour of the tip ofthe form I0 and slide off said form to clamp the glove directly and ilattherebetween without wrinkles or creases. During the remainder of thedescent of the rollers along the at surfaces 45 of the cam plates 25,the glove remains clamped and the stripping is completed. Finally,during the last part of such descent, the cam rollers move off the flatsurfaces 45 and are spread apart or separated under the iniluence of thespring 23 to release the glove which drops on to the belt 3I and isconveyed out of the machine. On the ascent of the slide 22, the camrollers are reengaged with the surfaces 45 and nally slide olf the guideplates 46 to be separated again by the spring 23 and to separate theclamping plates ready to receive the next form therebetween.

It will be noted that the clamping plates are yieldably mounted andhence are self adjusting to compensate for variations in the dimensionsof the work and of the parts, that being substantially at they do notdistort the garment gripped between them, that the stripping action isperformed by gripping one end portion of the garment and pullinglongitudinally thereon in a manner which is most efcient, and thatrolls, belts, gripping jaws and similar mechanisms are dispensed with torender the stripping mechanism positive and dependable in its action,regardless of whether or-not the garment, such as a glove having a righthand or a left hand thumb, has protruding parts or not.

Various changes may be made in the specific forms of the invention shownand described without departing from the spirit of the invention denedin the appended claims.
